Description

Powershift combined agricultural water pump

Technical field

The present invention relates to agricultural water pump technical field, more particularly to a kind of powershift combined agricultural water pump.

Background technology

It is known that agricultural drainage and irrigation can run into various complex situations：(1) such as require to carry out greatly farmland within the regular hour The irrigation and drainage of amount, conventional method are using multiple water pumps while working, and will certainly so cause the wasting of resources, increase equipment and manually Cost；(2) crops high-land run into, and the situation that water source physical features is relatively low, conveyed using centrifugal multistage pump multiple centrifugal pump；(3) for supporting Growing fish pond and substituting water needs flexible delivery, prevents from damaging fry；(4) immersible pump is miscellaneous for mud, impurity pasture and water and particle Thing is more sensitive, and screen pack need to be installed outside pump, and pasture and water impurity is filtering because suction all adsorbs after a period of time that works On the net, so as to causing pump work efficiency low or be stopped.Currently used agricultural water pump has a variety of shapes such as centrifugal pump, immersible pump Formula：Centrifugal pump structure is simple, lift is higher, and little with respect to water yield, the mechanical efficiency of water pump is about 70% or so, for mud For the sand larger killing rodents in farmland of amount content there is water pump serious wear, power consumption is big, when to fishpond water irrigation and drainage there is The problem of big to fry damage；When pump case internal memory has air, because the density of the density ratio liquid of air is much smaller and produce compared with Small centrifugal force, so that the pressure differential at ullage and Pump Suction Nozzle is not enough to interior liquid being pressed into pump, i.e. centrifugal pump Without suction capacity, prevent the problem of centrifugal pump is from conveying liquid (" air sinuses phenomenon ").Immersible pump is compared with above-mentioned centrifugal pump, no In the presence of " air sinuses phenomenon ", exterior lower-pump submersible pump is then directly from the pumping chamber after impeller or diffuser exit discharge liquor Body, the liquid cooling that motor is also pumped；Immersible pump is that liquid is done work, and liquid energy is converted mechanical energy into, in centrifugal force In the presence of water is discharged, the pump discharge is big, but lift is very low, and pump efficiency only reaches 68%, and energy resource consumption is larger；In addition, There is certain limitation to the solid dielectric pumped, insulating requirements are higher, can not meet to soar range request.From presented hereinbefore two kinds Agricultural water pump, which can be seen that them, respectively advantage and disadvantage, and it is mainly mechanical efficiency (energy-conservation) is low, security is poor and purposes is single etc. Problem.

Existing patent 200710098031.5 is entitled《A kind of spiral flow constant-pressure pump》Patent of invention provide one kind Spiral flow constant-pressure pump, including a pump case and an impeller, pump housing endophragm are circular arc, and impeller includes one with after a hub portion Cover plate, form integral multiple front vanes with back shroud on front side of back shroud and form one with back shroud on rear side of back shroud Multiple pairs of blades of body, each front vane are being bent and clockwise counterclockwise at back shroud circular edge Tilt, the bending sloping portion to be formed an angle with the preceding surface shape of back shroud, pair blade linear extension to impeller outward flange, this The vent centrifugal power that sloping portion back root part is bent when pump rotates is more than the vent centrifugal power of free margins before bending sloping portion, after The flow stream pressure of root also mutually should be higher than that the flow stream pressure of preceding free margins, and liquid flow path direction points to free margins by back root part, produce vertical To flowing, spiral flow is formed as wheel rotation produces rotational flow, enters back into the space between multiple front vanes on impeller, then Secondary pressurization, it acts on similar centrifugal multistage pump multiple centrifugal pump, so as to obtain the output of high-lift and constant pressure.
